An Update on Non Metastatic Castration-Resistant Prostate Cancer

Neal Shore | March 04, 2019

Androgen deprivation therapy (ADT) is the backbone of therapy for advanced prostate cancer patients who have failed primary interventional therapy.  Most of these patients will develop, through a potential multitude of resistance mechanisms, neoplastic cellular progression, and proliferation which subsequently leads to PSA relapse.2 Castration-resistant prostate cancer (CRPC), a rising PSA with castrate levels of testosterone alongside no radiographic imaging findings with conventional imaging (CT/Bone scans) are designated as non-metastatic (nmCRPC), or sometimes as M0CRPC.

Androgen deprivation therapy (ADT) is the longstanding initial treatment for advanced hormone-sensitive prostate adenocarcinoma. Nonetheless, patients who are initiated on ADT will invariably progress by developing prostate cancer cellular clonal populations, which creates a phenotype of more castrationresistant disease with more aggressive biology.1

For men with non-metastatic, castration-resistant prostate cancer (nmCRPC), who are invariably at risk of metastasis, the PROSPER trial clearly demonstrated that combining enzalutamide to androgen-deprivation therapy (ADT) resulted in prolonging metastasis-free survival by a median of 22 months compared with ADT plus placebo

When patients receive a diagnosis of cancer it can be devastating. Suddenly their world is turned upside down, populated by doctors, diagnostic tests, and treatments.

The standard process for newly diagnosed patients with prostate cancer is a chronologically linear and often one-dimensional process managed by urologists.3

Since Drs. Huggins and Hodges demonstrated the androgen dependent nature of prostate cancer in the 1940’s, androgen deprivation therapy (ADT) has been the mainstay treatment (albeit not curative) of advanced disease.
